Maria Gertrudis Swakhoven (1870-1945) was placed under guardianship

Maria Gertrudis Swakhoven was born on April 8, 1870, in Sittard, Limburg, The Netherlands. Her parents are (Maria) Margaretha Clemens (1843-1917) and Martinus Hubertus Swakhoven (1838-1904). He was a son of Hermanus (Herman) Swakhoven - who may have originated in Cleves in Germany - and his wife Maria Ida Olmans who originated in Nieuwenhagen.

Maria Swakhoven was married on September 12, 1899, to veterinarian Leonard (“Leo”) van Kempen. Bride and groom were both aged 30. Leonard was born on September 1, 1869, in Echt, Limburg, as eldest son of Jacobus Hubertus van Kempen en Maria Catharina Elisabeth Hubertina Joosten.
After giving birth to 3 children (with one dying while still baby in 1905), Maria was - by order of the court in Maastricht - in October 1906 placed under guardianship due to “sillyness”. At the time she was pregnant once more.

Nederlandsche Staatscourant, 29-1-1906: Maria Swakhoven is placed unter guardianship

Apparently, Maria's “sillyness” was no reason for her husband to stop having intercourse with her, because Maria gave birth to a fifth child in 1908.
These are the children of Maria Swakhoven and Leonard van Kempen:

1. Jacques Martin Leon, born on August 7, 1900, in Sittard. He was married on June 17, 1924, in Evergem, Belgium, to Suzanna Elisa Antoinette van Trappen. She was born in Evergem as daughter of Leonard Vantrappen and Emma Maria de Muijnck. Jacques died in Sittard on August 7, 1968.
2. Maria Helena Margaretha Hubertina, born on April 8, 1902, in Sittard.
3. Maria Elisa van Kempen, born on September 7, 1904, in Sittard. She died there on April 17, 1905.
4. Josephina Maria, born on January 10, 1907, in Sittard. She died there on February 26, 1910.
5. Piet, born on March 14, 1908, in Sittard.

Barend Booi (21) died in 1947 in Indonesia

Following World War II, the Royal Netherlands East Indies Army (KNIL) launched a military campaign in 1947 to try to re-establish Dutch control of Indonesia. The infantry regiment 4-11 departed on 5 February 1947 on the "Johan van Oldebarneveldt" for Indonesia, where it arrived on 5 March 1947. The regiment consisted of young boys recruited for obligatory military service, among them was Barend Booi. 
While fighting 4 kilometers west of Mangoenreja, Indonesia, Barend Booi died on 22 November 1947, aged 21. The death of Barent Booi was registered on 12 April 1948 in Dubbeldam, Holland. The Dutch military efforts to re-establish their colony failed, and The Netherlands recognized Indonesian independence on 27 December 1949.
